Answer:
93 °F
Step-by-step explanation:
At 7 am, the temperature was 55 °F + 2×7 °F = 69 °F.
At 10 am, the temperature was 69 °F + 3×8 °F = 93 °F.
Since the temperature was constant until 3 pm, it was 93 °F at noon.
Answer:
9.257
Step-by-step explanation:
7 goes into 64 nine times with the remainder of 1. Bring the decimal point up and the 8 down. 7 goes into 18 two times with the remainder of 4. 7 goes into 40 5 times with the remainder of 5. 7 goes into 50 7 times. That equals 9.257.
Have a nice day!!!!!! :-)

Answer:
, in degrees
Step-by-step explanation:
The secant of an angle is given by:
In this question:
So
In the first quadrant, the angle that has cosine of 1/2 is 60º.
The cosine is negative in the second and in the third quadrant.
The equivalent angle to 60º in the second quadrant is of 180º - 60º = 120º.
The equivalent angle to 60º in the third quadrant is of 180º + 60º = 240º
So the values of in the interval are:
, in degrees
